Unlocking broads / Earning slayer points

Skillers can obtain slayer points via tuska masks, which are made from tuska mask pieces dropped by airuts. They are only tradable for other pieces, which means that a cber needs to leave the mask pieces on the ground for the skiller to loot. Drop trading or death trading via familiar no longer works. 15 masks (75 mask pieces) are required in total to unlock broads or slayer rings.
